共济失调(躯干震颤及步态不稳)为儿童细菌性脑膜炎的少见并发症。作者们报导298例中有8例(2.7%),其他症状有长期发热、长期低钠血症或脓毒性关节炎(6例)。引发脑膜炎的病原体多为嗜血性流感杆菌、肺炎球菌和脑膜炎双球菌。对此8例患儿作了神经学、听力学及前庭系统详细检查,发现7例有严重感音性聋伴共济失调,3例有电眼震图异常。Liebman推测共济失调系脑膜炎并发浆液性迷路炎,以致迷路功能丧失,还可能存在小脑和脑干损伤。细菌性脑膜炎多用氨苄青霉素及氯霉素治疗,但这类药物似与共济失调无关。步态不稳症状可在数月或数年内逐步改善。
Ataxia (torso tremor and unsteady gait) is a rare complication of bacterial meningitis in children. The authors reported 8 out of 298 patients (2.7%) with other long-term fever, long-term hyponatremia or septic arthritis (6). Most of the pathogens causing meningitis are Haemophilus influenzae, pneumococcus and meningococcus. Neurological, audiological and vestibular systems were examined in eight patients. Seven patients had severe sensorineural deafness with ataxia and three had electrical nystagmus abnormalities. Liebman speculated that ataxia meningitis complicated by serous labyrinthitis, loss of function lost, there may be cerebellar and brain stem damage. Bacterial meningitis and more ampicillin and chloramphenicol treatment, but these drugs seem to be ataxia nothing to do. Unstable symptoms can be gradually improved in months or years.
